This interactive sunburst plot lets you browse the tree-like hierarchy of CATH.

The innermost layer splits CATH into
the 4 main CATH Classes. Successive layers split these Classes into Architectures, Topologies and Homologous Superfamilies.

Hovering over each sector provides a summary of the node in the center of the plot. Clicking on a sector will "zoom in"
on that node by replotting the chart with
the selected node at the center. A more detailed summary of that selected node is also displayed in the "Selected Node" panel
on the left.
